I made these as a Girl Scout in the 1960s. We used a tuna can instead of an altoids tin. They were called Buddy Burners. We made a "stove" from a #10 can and used the burners to cook hamburgers. I recently made one from a small can that I had used the side-cutting can opener to remove the lid. Now I can use the lid to put out the flame, as well as for transporting the burner.
